UMI Performance 82-92 GM F-Body Front Weight Jack System 850lb Street Handling
Upgrade your 1982-1992 GM F-Body's suspension with UMI Performance's Front Weight Jack System, designed for street handling and track performance. This system replaces the factory spring with a tough, adjustable weight jack bucket and a custom-wound ultra-premium performance spring.
With this kit, you'll get up to 2.5" of lowering from the factory height, and the adjustment bucket features an extra-thick 1/4" base to resist bending under competition forces. The ultra-smooth ride height adjustment is made possible by the acme bolt and industry-exclusive thrust bearing system, making ride height changes a breeze at the track.
The custom-designed 850 lb/in springs offer a crisp ride suitable for back road corner carving and daily driving. This kit provides the ride height adjustability of a coilover while still allowing maximum tire clearance around the strut.
- Maintains factory clearance around the strut and allows maximum tire and wheel width
- Pairs nicely with UMI Afco, Viking, or Koni strut
- Fits UMI K-member and Factory K-member (may not work on other brands)
- Acme thread and thrust bearing for easy ride height adjustment
- Adjustment completed easily with ratchet and 3/4" socket
- Strong 1/4" thick construction, CNC laser cut USA steel
- Allows independent front corner weight tuning
- 850 lb/in premium racing spring
- 0 to 2.5" lowering
- Anti-rotation tab
